I am still in the waiting room but unbeknownst to me I have had rheumatic heart disease for many years. Many of my teeth are crowned and I have one dental implant.
I can vaguely recall being given antiobiotics AFTER a few procedures. The only one that I know I had them before as well was the implant. The endodontist said he wouldn't consider doing it any other way- and this was before I knew of any valvular problems. Except for the long wait after the extraction while waiting for bone to fill the space to ready it for the implantation, I didn't have any problems. It seems the whole process took close to a year. It didn't have any more bleeding than having any other tooth pulled. Remember though, I was not on coumadin so I don't know if this helps you or not.
